"They did a nice job recognizing there was an issue and calling the authorities," city police Sgt. Christopher Goodnow said. "They were very helpful and forthcoming with anything we needed there."

Lt. Todd Boucher said police were obtaining a search warrant for the room.

"We are investigating what we suspect to be a meth lab," Boucher said.

Goodnow said firefighters were able to remove dangerous materials from the room. Two employees were treated for what Goodnow said were not life-threatening injuries.

David Roedel, co-manager of the hotel's owner, Roedel Companies, said Friday night that a room had been reserved for two nights and, when the occupants asked for two more nights, employees entered the room to clean it and conduct a security check per the company's policy. They noticed an unusual odor and "hazardous materials" in the room and the hotel's general manager called the police and fire departments, he said.

"I give all the credit in the world to our professional staff," Roedel said. "Without them sticking to policy and procedures, this might have gone unnoticed for the duration of their stay."

Goodnow said no arrests have been made in connection to the hotel incident. He said two people were arrested on "unrelated" charges, but did not have their names as of Friday night.

Roedel said this is the first time he can remember an incident like Friday's happening at the hotel. He said the hotel remained open throughout the incident.
